Urban-rural disparity in cancer mortality and changing trend in Tianjin, China, during 1999 and 2016

Abstract

Objective Compare the urban-rural disparity in cancer mortality and changing trend during the past 18 years in Tianjin, China. Methods Cancer death data were obtained from Tianjin All Cause of Death Registration System (CDRS), which covers the whole population of Tianjin. We calculated and compared the constituent ratio of cancer deaths, age-standardized mortality rate(ASR)and changing trends between urban and rural areas. Results From 1999 to 2016, a total of 245,744 cancer deaths were reported, accounting 21.7% of all deaths in Tianjin. The ASR of total cancer mortality was higher in urban areas than in rural areas. A total of 33,739 persons were avoided dying of cancers in rural area compared to the urban death level from 1999 to 2016, which was 40.1% compare to the current level of rural areas. But the gap between urban and rural areas became narrowed gradually. The urban-rural ratios (urban/rural) of total cancer mortality changed from 1.76 (125.7/71.5)[95%CI,1.67,1.84] in 1999 to 1.11 (99.6/90.0)[95%CI,1.06,1.15] in 2016. The ASR of lung, liver and esophagus cancer became higher in rural areas than in urban areas in 2016. Conclusion Cancer transition was obviously occurred in Tianjin and showed different speeds and big gap between urban and rural areas. Much more attention was needed to pay in rural areas which still have increasing trends in most cancers mortality recently.

Spatial and temporal analysis of liver cancer mortality in Yunnan province, China, 2015–2019

“…Urban-rural differences in risk factors (HBV infection, aflatoxin intake) exposure, socioeconomic development, hygiene status, and accessibility to health care (including treatment accessibility) may collectively contribute to this discrepancy in liver cancer mortality ( 29 , 30 ). Based on gender, a higher liver cancer mortality had been found in males, also consistent with the findings of previously published Chinese studies ( 31 , 32 ). Males reported higher levels of exposure to some identified behavioral risk factors of liver cancer, such as smoking and alcohol abuse ( 33 , 34 ).…”

Urban-rural disparities in the healthy ageing trajectory in China: a population-based study

“…In terms of family structure, a large number of left-behind children (whose parents went to cities to earn money) and older empty nesters have been increasingly common in rural areas due to population mobility brought about by socioeconomic transformation [ 10 , 11 ]; there are differences between urban and rural populations in terms of the frequency of contact with children [ 12 ] and economic interactions with children [ 13 ]. In terms of personal life, rural populations differ from urban populations in smoking rates [ 14 ], alcohol consumption rates [ 15 ], and utilization of medical checkups [ 16 ]. In addition, there are differences in healthcare resources between urban and rural areas [ 17 ].…”
